2. Description of the Related Art Conventionally, an operator is required to carry out indoor work such as attaching a board to a ceiling or an inner wall of a building, attaching a ceiling cloth, exterior wall construction, exterior work such as painting. It is necessary to build a scaffold of the required height.

As for the assembly of such scaffolds, those having various structures are used, for example, there is one in which scaffolds are assembled by pipes and scaffold plates are installed at necessary places, and stepladders are arranged at regular intervals. However, there are some scaffolds constructed by erection of scaffolds between them, and in addition, a stage scaffold in which pedestals can be folded and connected freely under a certain size of scaffolding plate is manufactured in advance. There is a scaffold in which plates are arranged at predetermined intervals, and a separately manufactured flat plate stage is installed between the plates to form a stage having a certain size as a scaffold.

[0004]

However, these conventional scaffolds have the following drawbacks.

A scaffolding with a pipe cannot be assembled and disassembled unless it is a professional, and it has to be constructed indoors or outdoors by straddling the assembled pipe at a work place, which lowers the work efficiency and climbs to the work scaffolding. However, it has a drawback that it requires an auxiliary ladder or the like.

In the structure of the scaffolding assembly in which the stepladder is arranged and the scaffolding board is installed between them, there is a drawback that it takes a lot of time to assemble the scaffolding, there is a concern about the strength after the assembly, and the assembly work is troublesome. Also, when scaffolding boards are laid continuously, there is a drawback that there is a step at the abutting part of the edge of each scaffolding board, which hinders the work. However, there is a drawback in that it is not easy to move while holding the scaffolding structure when it is desired to move in any direction.

In a scaffold assembly structure in which stage scaffolds are arranged and a flat stage can be installed between them to form a large stage, the number of assembly members is large, a certain level of skill is required for assembly, and safety after assembly is high. There is also a problem that there is a problem that a step occurs at the butting portion of the flat stage, and also that the lateral movement of the scaffold cannot be easily performed, and there is also a thing in which the height of the pedestal can be adjusted. However, it has a drawback that the adjustment allowance is rough and it is impossible to hold and install the horizontal stage on the uneven floor surface.
